How a state pays for itself, and who is asked.
The Citroën SM is a high-performance coupé produced by Citroën from 1970 to 1975, featuring a 2.7 L V6 engine and front-engine, front-wheel-drive layout. It was developed as a Gran Tourer using Maserati's engine technology and Citroën's suspension, debuted at the 1970 Geneva Motor Show, and sold initially in France in September 1970. All factory-produced units were left-hand-drive, and its design was constrained by French puissance fiscale taxation.
A one-off 1979 concept built to show off Newport Pagnell—and chase a title it never claimed.
The Chrysler Turbine Car was an experimental two-door hardtop coupe designed by Elwood Engel and built by Chrysler with bodywork by Carrozzeria Ghia. It used the A-831 turbine engine, was produced in 55 units between 1963 and 1964, and featured power brakes, power steering, and a TorqueFlite transmission. All were finished in 'turbine bronze' paint.
The Ford RS200 is a purpose-built homologation special: mid-engined, all-wheel drive, plastic-fiberglass body by Ghia, built by Reliant in Shenstone to meet FIA Group B’s 200-unit rule. It exists only to enable a rally car—not as a design statement, luxury product, or road-going evolution.
The Firebird I is a 1953 GM concept car designed by Harley Earl. It was the first gas turbine-powered car tested in the United States. It features a single-seat cockpit under a bubble canopy, a bullet-shaped fiberglass fuselage, short wings, and a vertical tail fin. It was built for the 1953 Motorama show. GM never intended it for production.
